June 14, 1932. D. HERNDON WINDOW SCREEN Filed Sept. 5, i951 Patented June 14, 1932 LANEY D. HERNDON, 0F COLUMBUS, GEORGIA WINDOW SCREEN Application filed September 5,1931. Serial No. 561,438.

The present invention relates to improvements in window screen constructions, and has for an object to provide an improved screen construction carrying a fitting for the operating handle of casement windows, whereby such handle will fit through the screen and be exposed for operation upon the interior of the room.

Another object of the invention lies in providing an improved screen fitting so constructed and arranged as to freely receive the operating handle without causing pulling or dragging of the wire of the screen, and which involves an adapted plate for placing over the handle subsequent to the arrangement of the handle through the screen, such adapter plate fitting closely about the handle but allowing the turning movement of the handle while efiectually preventing the entrance of insects or the like.

A further object of the invention is to provide a neat and attractive fitting for screens where the operating handle of the casement windows extends through the screen.

A still further object of the invention is to provide an improved marginal edge construction of screen so as to enable the same to properly fit against casement windows.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is an interior view in elevation of a room having casement windows and a screen constructed according to the present invention.

Figure 2 is a horizontal section taken on an enlarged scale on the line 22 in Figure 1.

Figure 3 is a fragmentary perspective view of the screen and improved fitting prior to assembly.

Figure 4 is a vertical section taken on the line 4l4 in Figure 1.

Figure 5 is a fragmentary perspective view of the casement window and screen construction.

Referring more particularly to the drawing 10 designates the wall of a building or other construction have casement windows therein involving the window frame 11 and the hinged casement window members 12.

These casement windows are operated by a shaft 13 having a handle 14 extending upon the interior of the room where it may be accessible for locking and unlocking the windows by a rotary movement of the handle and shaft 13. V

The improved screen construction is adapted to fit entirely over the window on the inside thereof or inside of the easement window members 12 so that the operating and locking means must extend through the screen to be operative upon the inside of the window.

In this way the window screen may extend continuously over the entire window and the screen need not be raised when the window sashes are to be opened or closed or locked or unlocked and consequently no insects will ever have an opportunity to gain the room inside.

The screen material is indicated at 15 the same being carried by a suitable rectangular frame hereinafter more fully referred to. In a central portion of the wire mesh 15 about the operating shaft 13 is secured a fitting. This fitting consists of a small rectangular frame 16 of sheet metal or other appropriate material composed of folded strips having openings 17 therethrough to receive screws or other fastening means 18 passing through the wire mesh 15 which overlaps the frame members 16. This wire mesh fits between the frame members 16 and a flange 19 of a back plate 20. This flange 19 is rectangular in construction and of substantially the same dimensions as the frame 16 whereby tofit against the screen 15 on the opposite side to the frame 16 and to receive the fastening screws 18 therethrough.

In this way the fitting is held tightly upon the wire mesh 15 and the wire mesh is reinforced at both sides of the opening. The flange 19 is ofi'set from the plane of the back plate 20 by side walls 21 which extend at right angles rearwardly from the back plate 20'. The flange 19 is turned outwardly at substantially right angles from the walls 21. Centrally or atother desired point, the back plate 20 is formed with an opening 22 adapted to fit about the operating shaft 13 and its handle, which handle is usually pivoted to the end of the shaft 13 so as to admit of swinging the handle lengthwise out in alinement with the axis of the shaft 13, thus permitting both the handle 14 and the shaft 13 to be received through the opening 22, which opening is made of a diameter appreciably greater than the external diameter of the shaft 13, for which see Figure 2.

A front or adapter plate 23 is fitted to the outside face of the back plate 20 and such adapter plate has an opening 24 therethrough smaller in diameter than the opening 22 in the back plate. The opening 24 in the front plate 23 is preferably of a size to accurately fit over the handle and shaft 13, whereby to exclude insects and to avoid the entrance of any flying or crawling creatures but at the same time permit the shaft 13 to be freely rotated in the operation of the windows.

The plate 23 may be beveled off as indicated at 25 along its edges yielding an attractive appearance and blending with back plate 20. The front plate 23 is provided with openings 26, which openings may be two or more in number and through which pass the screws or other fastenings 27 by which the front plate 23 is held to the back plate 20.

Referring more particularly to Figures 4 and 5, screen material 15 is shown as being secured at its outer end in a frame member composed of an internal wide flange plat-e 28 of rectangular or other form. This flange plate 28 is formed with an inturned edge 29 and a folded wall 30 having an inturned edge 31. The edges 29 and 31 are spaced apart and opposed to each other and adapted to receive therebetween the filler strip 32 by which the screen material is bound in place.

In accordance with the invention the plate 33 is welded or otherwise secured to the members 28, 30 and this plate 33 is provided with an outturned outer flange 34: and with an inturned curled free edge 35 disposed substantially in the same plane with the screen material 15. This will provide for properly fitting of the the screen against the casement window, the curled flange 35 giving the additional purchase.

In the use of the device, the frame 16 and the back plate 20 may be secured to the screen during the manufacture thereof. Thus a relatively large opening 22 will be presented to the operating members 1 1 and 13 when the screen is applied in place and therefore the screen may be put in place on the window without causing the dragging of the mesh 15 in order to get the opening 22 at a proper position to fit over the operating members. It will be understood that there is slight variation in the positioning of these operating members and also there may be slight variation in the placing of the fittings upon the screen member and the opening 22 will compensate for all these variations and still enable the screen to be put in place without detriment to the wire mesh thereof.

After the screen is put in place the front plate 23 is fitted up over the operating shaft 13 and up against the back plate 20-. The back plate 20 may then be bored with holes marked by the holes 26 of the front plate so as to receive the fastening screws 27. The front plate 23 may, of course, go on in true axial alinement with the shaft 13 and, therefore, its opening 24 may be of a diameter to accurately fit the external diameter of said shaft 13.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims What is claimed is 1. An improved window screen construction comprising screen mesh, a small frame carried by the mesh, a backing plate attached to the m'esh and said frame and having a relatively large opening therein for receiving the operating member of the Window lockin device, and a front plate removably fitted to said back plate and having a smaller opening therein snugly fitting about said operating member.

2. A window screen construction comprising a body of screen material having an opening therein, a frame fitting about said opening in overlapping relation with the screen material, a back plate having a flange fitting against said screen material opposite the frame and secured thereto, said back plate having an opening therein larger than the window locking device which projects therethrough, and a front plate fitted against and secured to said back plate and having an opening therein adapted to snugly receive said operating member.

3. An improved screen construction comprising a body of screen mesh material having an opening therein, a frame fitted about said opening at one side of the screen material, a back plate having offset edge Walls and an outturned flange fitted against the screen material opposite said frame and removably secured thereto, said back plate having an opening therethrough larger in diameter than the diameter of the Window locking device which projects through the opening, and a front plate having a beveled edge and opening therethrough for fastening, said front plate also having an opening smaller in diameter than the first named opening for fitting snugly about the operating member but allowing rotation thereof, and fastening means passing through the holes in the front plate and secured in the back plate.
